WHEEL-GUARD.

Specification of Letters Patent.

llatented Feb. 24:, 19t-l.

Application filed December 1 4, 1932. Serial No. 736,839.

To all 107mm t may concern:

Be it known that l, l/VILLIAM Cotnrrnnr Pieeo'rr, a subject et the King of Great Britain and Ireland, and a resident et London, England, have invented certain new and useful Improvements in llVheel-Gfuards; and l do hereby declare the following to be a full, clear, and exact description ot the same.

This invention relates to iniprovements in life-guards ior the road wheels oil motor cars and other sell? propelled vehicles.

The guard comprises a deiiending guard member in the form of a leaf spring mounted in Jfront of the front or back road wheel above the road surface, with facility oiI rearward, upward and preferably lateral movements, on the front wheel stub or movable axle or other part of the vehicle so that the guard member will, under normal conditions, remain in front of its wheel.

in the operation of the device, when the guard member collides with a fallen person, it prevents'the wheel from passing over him, and when the guard member collides with an immovable object, such as a curb or irregularity of the road surface, the guard member' yields rearwardly, or upwardly, or laterally, by reason ot' its construction and method of mounting, so that no damage is done.

rlhe invention is illustrated in the accompanying drawings, as applied by way oit example, to the chassis of a motor omnibus, and its application to other vehicles will be obvious therefrom.

Figure l is a side elevation taken at the 'liront end ot the chassis, the suspension nings being omitted and showing the guard member mounted. in liront of the 'liront road wheel; Fi Q is a front elevation partly in .section ot the parts shown in Fig. l; Fig. 3 is a plan; Fig. t is a sectional elevation on an enlarged scale showing the guard member' mounted with facility of lateral movement; Fig. 5 is a si de elevation, partly in section, oit a modification showing the guard member mounted in front oit the front road wheel; Fig. 6 is a perspective view ofl the parts shown in Fig. 5; and Fig. 7 is a sectional elevation on an enlarged scale showing the guard member slidably mounted in a socket or guide.

a represents the frame oi the vehicle; o the suspension springs; b the iront wheel stub or movable axle movable around the vertical pin, b, supported by the front wheel stationary axle, b2, in customary manner; and c the front wheel.

fl represents a depending guard member which is made in the term oie/a leaf spring, and is mounted at the 'front end ot an arm or lever, d', which may be adapted to turn up or down on a pivot; (Z2, on a bracket or carrier, c, clamped or otherwise made fast, for example, to the front wheel stub or movable axle, Z). The arm is preferably provided with and adjustably supported by a setserew, f, bearing against a stop, c, preterably on the bracket, and is normally retained in its lowest position by a spring. y, connected to the arm at g, and to thebracket at g2. rEhe spring g is secured by its ends being formed with eyes which encircle cross bolts on the arm as shown at g1 and g2 aforesaid. The spring operates by bearing at its center part against the pivot (Z2 and tending to bring its 'forward end down ward. The guard member is mounted in a socket, cl3, on the arm, by means oit' a pivot, L, so as to have facility oi' limited lateral n'iovement, and is normally held directly in front o the wheel by a spring, e', connected to the guard at t", and to the arm, (Z, at The head of the guard member is specially shaped, as shown in Fig. e to accommodate and limit the lateral movement.

In the modiiication represented in Figs. 5, G and 7, the head of the guard member, (l, is mounted as a slide in a vertical or approximately vertical socket or guide, d'2, integral with the bracket, or carrier, e, to provide for up and down movement, and a spring or springs, f, is or are provided to resiliently keep the guard member, (l, in its lowest or normal position above the ground, the guard members, (Z, being provided with stops, (Z5, adapted to engage abut-ments, d, on the guide. In this case, 'the lateral movement oit the guard member is provided for by its own resiliency. The guard member may be provided with rollers or small wheels` als, at its lower end, and with a pad or cushion, (Z7.

vWhat l el aim as my invention and desire to secure by Let-ters Patent is l. ln a vehicle wheel liiie guard, in combination, a carrier mounted so as to partake of steering movements of said wheel, a member adapted to rise and fall in relation to said carrier, spring means for normally retaining said member in its lowest position,

and a guard member in the form of a leaf spring dependino in front of the wheel and connected at its upper end to said first-mentioned member, substantially as described.

2. In a vehicle wheel life guard, in coinbination, a carrier mounted so as to partake of steering movements of said wheel, a forwardly extending lever pivoted at its rear end to said carrier with facility of rising and falling movements, a guard member in the form of a depending leaf spring pivotally connected at its upper end to the forward end of said lever so as to have facility of lateral movement, and spring means for normally retaining said guard member in front of the wheel, substantially as described.

3. ln a vehicle wheel life guard, in combination, a member extending at the side and in front of said wheel and mounted so as to partake of steering movements thereof, a socket at the forward end of said member, a guard member in the form of a leaf spring depending` from and pivotally mounted in said socket with facility of limited lateral movement, and spring means for normally retaining said guard member in position in front of the wheel, substantially as described.

el. In a vehicle wheel life guard, in combination, a carrier mounted so as to partake of steering movements of said wheel, a fora guard member in the form of a depending leaf spring connected at its upper end to the L,

forward end of said lever, substantially as described.

ln a vehicle wheel life guard, in combination, a carrier mounted so as to partake of steering movements of said Wheel, a forwardly extending lever pivoted at its rear end to said carrier with facility of rising and falling movements, spring means for normally retaining said lever in it-s lowest position, a set screw and stop for adjusting the downward movement of said lever, a guard member in the form of a depending leaf spring pivotally connected at its upper end to the forward end of said lever so as to have facility of lateral movement, and sprinO means for normally retaining said guard member in front of the wheel, sub stantially as described.

ln testimony whereof I aflix my signature, in presence of two subscribing witnesses.
